2. Stand preparation

3. Load

4. Results analyze

● Varnish doesn’t cache anything

● no ESI

1. Project A after optimization

● Enabled memcache

● Enabled ESI

● Varnish is configured

● Cache per roles

Initial data:

Example

Response time - “before”

Example

Response time - “after”

Example

Average value “before”: 9000ms

Average value “after”: 330ms

Results - response time

Example

Throughput - “before”

Example

Throughput - “after”

Example

Average value “before”: 6.2 transaction/sec

Average value “after”: 114 transaction/sec

Results - Throughput

Example

Hits per second - “before”

Example

Hits per second - “after”
